To make Philips more lean and nimble has taken a rigorous monitoring of its entire portfolio of products and markets combined with a ruthless willingness to jettison weaklings and poor performers such as the home entertainment businesses, and to concentrate instead on higher-margin market leaders.

Mr Van Houten picked new managers at each of the company's three core businesses - consumer lifestyle, healthcare and lighting - and is shaking up a stodgy culture in a firm that once led in R&D but sometimes fell short in the marketplace.

The company which first experimented with televisions and radios later lost out in the videotape wars of the 1970s and 1980s and did not react quickly enough when consumers shifted online for their music and other entertainment.

Mr Van Houten has also cut jobs and overheads, including office space and IT systems, scaled back inventory to free up cash flow, and launched a 2 billion euro share buyback.

The strategy has started to pay off. The divestments and four consecutive quarters of better-than-expected results have pushed the stock to its highest level since March 2011, just before Mr Van Houten officially took over as CEO, as Philips appears to be on track to achieve its 2013 targets.

"Exiting lifestyle entertainment for me is the real mark, these guys invented a lot of these consumer electronics we know, that is part of the Philips legacy," said Scott Cobb, principal at Southeastern Asset Management which is Philips' biggest shareholder with about 6.5 per cent of the stock.

"For them to say 'this is a business that is marginally profitable, struggling with declining revenue and does not have scale to compete' sends a massively strong signal that this company and its management are not the old Philips."

Cobb said the 2 billion euro share buyback was also a strong buy signal because it showed the management was confident of delivering cost savings and pushing through change.

There is plenty of room for further improvement.

By some measures, such as the ratio of enterprise value (EV) to earnings before interest, tax, depreciation and amortisation (EBITDA), Philips looks undervalued against German conglomerate Siemens and General Electric, its rivals in the field of lighting systems and hospital equipment.

Starmine puts the forward 12-month EV/EBITDA for the Dutch firm at 6.8, versus 7.7 for Siemens - and 18.7 for GE, whose figures analysts say are distorted because of its finance activities. Two French firms in the capital goods sector, Schneider Electric and Legrand, trade on multiples of 9.1 and 9.5 respectively.

Philips is also cheaper than two small European firms which compete purely in the home appliances sector. SEB of France, which owns the Moulinex brand, and De'Longhi of Italy, are valued at multiples of 7.2 and 7.9 respectively.

Based on other ratios such as price/book value, and EV/revenue, Philips ranks at the lower end of the group's range.

And with roughly one third of Philips' units still underperforming and in need of turnaround, according to Mr Van Houten, there should be further upside for investors.

"There is much more potential to unlock. We need to stay at this for five years," Mr Van Houten said, just two years into the turnaround, adding that too many companies "stop too early" when it comes to shaking up their business.

Red-amber-green

Mr Van Houten became chief executive in April 2011, but during his months as CEO-in-waiting, he took a whirlwind tour of what was soon to become his global empire.

Stunned by the sheer number of different products available in a myriad of different markets, he realised the group had proliferated and had little inkling of which of these combinations made or lost money.

He worked closely with his chief financial officer, Ron Wirahadiraksa, and with chief strategist Jim Andrew, a former Boston Consulting Group partner who had worked in India and Singapore, to come up with his plan.

Using what he describes as a "dashboard" - a computer model that monitors hundreds of combinations of products and the markets where they are sold - he can keep track of profits, sales, market share and supply chain efficiency for anything from medical equipment in Malaysia to salad dicers in Russia.

Each business and market combination appears in red, green or amber, according to performance, and is further scrutinised for ways to squeeze more value out of it.

Recognising that Philips could no longer compete with low-cost Asian manufacturers such as Samsung Electronics and LG Electronics when it came to televisions and audiovisual equipment, Mr Van Houten cut them loose.

The model isn't foolproof. High-growth countries are set high targets, but for example if growth hits 28 per cent, just short of a 30 per cent target, the targets may have to be eased slightly, Mr Van Houten says.

The consumer division's underlying margin for earnings before interest, taxes and amortisation has already improved to 11.7 per cent in the fourth quarter from 8.3 percent a year ago. With the sale of the low-margin audiovisual business, it should increase further, helped by its leading position in electric shavers and toothbrushes.

Overall, the consumer lifestyle division now accounts for a far lower percentage of group sales - 26 per cent in the fourth quarter, down from 36 per cent two years ago - while healthcare has climbed to about 41 per cent of group sales, up from about 36 per cent in the same period.

With home entertainment out of the way, the consumer division will focus on appliances such as coffee-makers, electric shavers, and "airfryers" which cook low-fat food.

Philips signed up Taiwanese actor and model Godfrey Gao to endorse its electric shavers in China, helping it to sell more than 10 million last year as it pushed into second- and third-tier Chinese cities.

In Russia, the company has adapted its salad-choppers to produce cubes because that is how Russians like their vegetables - and the dicers have proved a hit, Mr Van Houten said.

Historically, Philips had tied its fortunes to the developed markets of North America and Europe.

It was slow to exploit the rapid rise of emerging markets where billions of consumers craved a better lifestyle and higher standards of healthcare, and increasingly had the money to pay for it.

That's changing, if slowly. The share of sales derived from growth economies such as Brazil, Russia, India and China, as well as Africa and the Middle East, inched up to 35 per cent in the fourth quarter, from 33 per cent of the total two years ago, and is set to rise further, Mr Van Houten said.
